To all whom it may concern.-

' ofITexas, have invented a new and useful Telephone-Signal; and I dohereby declare the following to, be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit apper- This invention relates to certain new-and useful improvementsin a switchboard-drop of the visual signal for magneto system at thecentral office. of atelephone company; and, more particularly, theinvention consists" in the provision of a device, as hereinafterdescribed, claimed, and shown in the accompanying drawings, which may beeasily adapted in connection with a suitable switch-. boardof a magnetosystem.

Another ob ect of the in'vention is to provide a device of thischaracter whereby as a telephone call is made the armatureand indicatoris locked in the vision of the switchboard operator, andb inserting theplug of the telephone-nun; or which is called into thesoeket of t edevice it will absolutely restore the indicator and armature to itsnormal pgeition entirely by gravitation, thereby ma 'g the device veryefficient and springs which become non-serviceable.

The invention, as shown, is adapted for grounded systems; but it is tobe distinctly understood that the invention is not to be limited to anyparticular system, but may rises further objects ements, which will behereinafter set forth, and the novel. features thereof will be referredto by the appended claims. v

To obtain a full and correct understanding of the details ofconstruction and combina- The invention com tions of features, elements,and advantages, reference is to be had to the hereinafter set forthdescription, in connection with the accompanying drawings, whereinFigure l is a perspective view of the imshowing in a diaprovedswitchboard-drop, grammatic way the relative electrical connections ofthe operative elements. Fig. 2 is a longitudinal sectional view throughthe sw itchboard-drop with the plug inserted within the socket. Fig. 3is a diagrammatic view of the electric wiring of the sw itehboard-drop.Fig. 4 is a cross-section on the line 4 4 of Fig. 2, and Fig. 5 is adetail perspective View of the armature and indicator.

call is made and at the same night-bell circuit, as hereinafterdescribed.

The armature is made integral with the weighted indicator+rod 5, havingan iridicator-plate 6 ,at one end thereof, which is provided with asuitable telephone-number which designates a telephone to which theswitchboard is electrically connected. The indicator-rod is adapted tocooperate with the notch 7 of a vertically-oseillathrg releasing-bar 8,which is mounted upon the core of said magnet, as illustrated in theaccompanyin drawings.

The said lower end 9.f the. releasing-bar 8 only lies within the cut-away ortion whenthearmature is attracted, hich causes the indicator-rod to be throwninto engagement with the notch 7 of said bar.

There are two metallic strips 14 and 15 provided upon the under side ofthe base of the device,' said strips one another by suitable'insulatingmaterial. Said strips also form an electrical connection when atelephone-number is desired, which causes the armature to be attractedand the longest strip 15 makes an electrical connection with thetelephone that is called when the plug 13 is inserted within the socket.11 and at the same time cutsout the magnet by separating theplane-surface of the strip 15 from the contact-ppint 16 of the strip 14,as clearly shown in t e drawings.

The operation of the device is set forth as follows: As the receiver '17of the telephone 18 is lifted from the holder at the subscriberls,

being insulated from v through the wire-connection 22 between said post21 through thestriphl 5, through the contact-p01nt it, then through-thestrip- 14, and
